No drip siphon fed flat fan pattern nozzles are great where no liquid pressure is available and a thin coating is needed over a wide band. Since these nozzles are siphon fed, the compressed airflow draws the liquid in and mixes it internally. No drip atomizing nozzles have the added benefit of positively stopping liquid flow when the compressed air is shut off. No drip siphon fed atomizing nozzles are siphon or gravity fed for non-pressurized applications. (Model SF2010SS pictured.)
